Description of problem:

In RHEL6.4 version of IPA, I'm seeing internal errors when searching for delegations by group:

[root@rhel6-1 ipa-delegation-cli]# ipa delegation-find --group=gr1000
ipa: ERROR: an internal error has occurred

Version-Release number of selected component (if applicable):
ipa-server-3.0.0-15.el6.x86_64

How reproducible:
always

Steps to Reproduce:
1. Setup IPA server
2. kinit admin
3. ipa group-add mg1000 --desc=mg1000
4. ipa group-add gr1000 --desc=gr1000
5. ipa delegation-add delegation_find_positive_1000 --membergroup=mg1000 --group=gr1000 --attrs=mobile
6. ipa delegation-find --group=gr1000
  
Actual results:
ipa: ERROR: an internal error has occurred

Expected results:
returns delegation_find_positive_1000 listing

Comment 1 Scott Poore 2012-12-18 15:21:43 EST
Something confusing me here though.  When I run with --attrs=badattr it fails as expected instead of with internal error.

[root@rhel6-1 ipa-delegation-cli]# ipa delegation-find --membergroup=mg1000 --group=gr1000 --attrs=badattrs
---------------------
0 delegations matched
---------------------
----------------------------
Number of entries returned 0
----------------------------

[root@rhel6-1 ipa-delegation-cli]# tail -1 /var/log/httpd/error_log 
[Tue Dec 18 14:19:36 2012] [error] ipa: INFO: admin@TESTRELM.COM: delegation_find(None, attrs=(u'badattrs',), memberof=u'mg1000', group=u'gr1000', pkey_only=False, all=False, raw=False, version=u'2.46'): SUCCESS

So, does that means it searches for the attrs first, finds nothing, so fails before it has a chance to hit the code searching for group?
Comment 4 Martin Kosek 2012-12-19 04:39:44 EST
Thanks for the report. I will start from your last comment.

When we search with --attrs, we skip --group or any other following checks when this one fails because it is obvious that this particular delegation won't be included in the search result.

About the bug report itself, this is indeed a bug. I will clone it upstream.
